Losing Lift

[mwarren]

I have 1 old battery and 2 brand new batterys and my motors are fairly new, the problem I have, happens from the time I start flying till I stop flying so I dont think it is a battery issue or a motor issue.

When I get off the ground and flying, I keep the power the same to the motors and the motor and prop noise seems to sound the same so I dont think I am losing power but the heli acts as though its lost some power and starts sinking so I give more power and it goes back up. This is a steady issue from beginning of the flight to the end of flight. I am back and forth with the throttle.

Is tis normal for all Blade CX helis, I seem to be adjusting throttle so much I dont have the time to try forward flight or any other moves with the Blade CX

Seems like I need more lift out of the factory blades, maybe adjust them for more lift.

Make sure your AC and any fans are turned off. Also, if you are flying in a confined space, the wash from the rotors will feedback upon themselves. The heli creates and is effected by its own 'wind' in close quarters.

I was in a gym with no wind or air movement and I try to fly at or around 6 to 8 foot above the ground. The heli stills goes up and down like a yoyo.
